Well that gun was originally an SR-16, so it was already wired to the back. After 2 attempts to install the crane stock I gave up and i am bringing it to a local airsoft shop to have them do it. I just stuck the stock on there for a picture But I really dont think it is that hard to rewire, if you are comfortable opening the gearbox you can just run 2 wires all the way from the gearbox to the crane stock. I have a guide if you want it.
